Title: Method of authenticating information, disk playback apparatus, and entertainment apparatus
Inventor: NODA SHINJI
IPC: A63F13/73
Filed: 1999-09-22
Abstract: A playback instructing unit in a disk playback controller has a function to instruct a CPU to play back an optical disk at different access positions in an absolute authentication process and an arbitrary authentication process. An absolute decision unit has a function to be activated by an absolute authentication instruction from the playback instructing unit and authenticate the decided result from an authentication decision means according to a first rule (which declares normal authentication based on a normal decision). An arbitrary decision unit has a function to be activated by an arbitrary authentication instruction from the playback instructing unit and authenticate the decided result from the authentication decision unit according to a second rule (which declares normal authentication based on an abnormal decision). Even if a special device which can normally authenticate an optical disk that should not be authenticated normally is connected to a disk access mechanism, the optical disk that should not be authenticated normally or the special device can reliably be detected to forcibly interrupt any process being carried out, so that the optical disk can effectively be prevented from being illegally copied.

Patent CA-2300529-A1 (CA)
Title: System and method for generating and playback of three-dimensional movies
Inventor: DEERING MICHAEL F
IPC: H04N13/363
Filed: 2000-03-13
Abstract: A system and method for generating and playing back three-dimensional (3D) movies are disclosed. The system is capable of partially rendering frames without relying upon exact viewpoint information. The partially rendered frames may be rendered to the extent possible without performing viewpoint-dependent processes, and then compressed and stored to a carrier medium. To reduce the amount of data to be stored, the viewer's possible viewpoints may be restricted (e.g., by defining a viewpoint-limiting volume or region). The resulting partially-rendered geometry data may be compressed using geometry compression. During playback, the compressed frames are read as a stream, and decompressed. Any final viewpoint-dependent rendering operations may then be performed (e.g., some lighting calculations and atmospheric effects, some fogging, specular highlighting, and reflections). A sensor such as a head-tracker may provide real-time viewpoint information that may be used by the playback system. After rendering, the frames are rasterized and then displayed in stereo.

Patent CA-2302668-A1 (CA)
Title: Tubular microwave applicator
Inventor: RISMAN PER O
IPC: H05B6/70
Filed: 1998-09-08
Abstract: An assembly for applying microwave irradiation to a load having a generally circular cross section. The applicator supports a dominant TM120 mode and the load is aligned with a central axis in the applicator, with each aperture of a pair of feed apertures diametrically opposed (for the circular cross-sectional case) or located on parallel opposed walls (for the polygonal cross-sectional case) with one of the pair of feed apertures positioned at 90 degrees with respect to the other pair about the axis. The applicator may be formed as a cylinder or as a polygonal prisms of the type having parallel opposed sides, such as those having a square, hexagonal or octagonal cross section. Means such as a microwave transparent tube or conveyor provide for positioning of the load in the applicator. In an alternative embodiment, two cavities are used, with one cavity associated with each of the two feed systems, and a means for conveying the load from the first cavity to the second cavity is provided. In one octagonal cross section embodiment, the two feed aperture pairs are located in one cavity.
Patent CA-2303833-A1 (CA)
Title: Genital lubricants with zinc to reduce irritation and allergic reactions
Inventor: KELLY PATRICK D
IPC: A61K31/765
Filed: 1998-07-17
Abstract: This invention discloses that certain types of zinc compounds, if added to formulations (such as condom lubricants and lubricant gels) that are applied topically to one or more genital surfaces during sexual intercourse, can reduce the irritation caused by spermicidal and/or microbicidal agents, which act essentially as toxins designed to kill various types of cells and microbes. Preferred zinc compounds include zinc lactate, zinc gluconate, zinc acetate, and other water-soluble organic zinc salts. In addition to reducing irritation caused by surfactants (such as nonoxynol or octoxynol) and other microbicides in topical genital formulations, zinc-containing additives can help stabilize and protect cellular membranes, thereby helping protect genital surfaces against damage caused by repeated exposure to agents that attack the lipid membranes that surround mammalian cells. Zinc-containing additives can also help accelerate the healing and closure of lesions or other skin breaches caused by spermicidal or microbicidal toxins, or by abrasion, rashes, sexually transmitted diseases, or other causes. Because of these effects, topical genital formulations containing spermicides or microbicides, and also containg a suitable zinc compound, can promote better skin tone and better genital health and hygiene, compared to similar formulations containing a spermicide and/or microbicide without zinc. In addition, zinc-containing additives can also reduce the risk and severity of allergic reactions to latex proteins in condoms.
Patent CA-2305910-A1 (CA)
Title: Combo afci/gfci with single test button
Inventor: MACBETH BRUCE F
IPC: H02H3/33
Filed: 2000-04-17
Abstract: A combination AFCI/GFCI includes a single test button which when pushed, tests both the arc fault and ground fault detection circuitry and the circuit interrupter. Closing the test button causes a simulated ground fault and enables a signal steering circuit. The steering circuit redirects the ground fault detector output to as arc fault simulator circuit which produces a simulated arcing pulses that are coupled, preferably by way of an extra winding, to an arc fault sensor transformer. The arc fault detector senses the arc fault simulator pulses coupled to the sensor transformer and, if everything is operating normally, triggers a switching device such as an SCR which activities a circuit interrupter. In this way, both the ground fault circuit interrupter and arc fault circuit interrupter functions are tested simultaneously, and the test is initiated by a single test button. When the circuit interrupter is not in the test mode, the steering circuitry is disabled and either a ground fault or an arc fault or both will independently activate the switching device and the circuit interrupter.
